Identify the reason that justifies the following statements. 19) 1=~4
20) 2+4+5 = 180
21) 5+7=180
22) 4+2=7
23) If CA bisects DCB, then 1 =~ 2
24) 3+7=180

Possible reasons:

A. Triangle exterior angle theorem
B. Vertical angles are congruent
C. Angle addition postulate
D. If lines are parallel, then alternate interior angles are congruent
E. If lines are parallel, then corresponding angles are congruent
F. If lines are parallel, then same side interior angles are supplementary
G. Definition of midpoint
H. Definition of angle bisector
I. The sum of the angles of a triangle is 180

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.

a farmer that lived in ancient egypt would most likely be barried in the sand, in the desert!

if i'm not wrong, i would say that the third angle has (72) because the three sides of all triangles have 180 degrees and if we subtract 180 - 62 - 40 = (72) / but i'm not sure about 40 yd.
